Zusammenfassung:	A power over Ethernet (PoE) system includes a device and a power sourcing equipment (PSE) device that is configured to couple to the device through an Ethernet cable. The PSE device detects, in response to the device being coupled to the PSE device, that the device is a powered device. Subsequent to detecting that the device is a powered device, the PSE device determines whether a powered device identifier has been received from the device. In response to determining that a powered device identifier was received from the device, the PSE device determines that the powered device identifier identifies an authorized powered device. The PSE device then identifies a powered device classification of the powered device, and provides to the device via the Ethernet cable, first power according to the powered device classification.
